1. International IEC electric standards, the breakdown voltage can be up to 50 KV after one pass filtration process to reduce oil aging damage caused by repeated heating.

2. The two stages high vacuum pumping system can meet the requirements of the vacuum drying of the transformers in the field of installation or maintenance, and at the same time complete vacuum degassing and dehydration treatment of the transformer oil greatly reduce water content.

6. Digital display intelligent temperature controller overcomes the traditional index type temperature controller can only set a heating point, the upper and lower limits can be set at 20~80 °C, which can display the instantaneous temperature of the oil more intuitively.

For the oil-immersed transformer, even the new transformer is used for 1-2 years, the transformer oil must be purified by Vacuum Transformer Oil Purification Machine to remove impurities, moisture, and harmful gases (mainly hydrogen-based gases), so that the used oil can reach new oil standards and reused. This also saves energy and production costs.
